China counts on Russia to support its views on international institutions and the "power shift" to Asia, in part because Russia is integrating itself within Eurasia.
China is becoming more dependent on Russian energy – 11 % of its imports, but that’s a welcome diversification from the Middle East, or from American liquefied natural gas (LNG) at a time of trade tension. As of 2019, Russia is becoming China’s largest supplier of oil. But neither Russia nor any production cartel control the price any more: the greatest dependency, for cash, is still Russia’s. China’s experts do not hide their country’s hand too much, when they explain that oil and gas resources from Central Asia can also compete with Russia’s.
